Problems solved by technology

The research on the breeding technology of broccoli in our country started relatively late, and some techniques still need to be perfected by using self-incompatibility lines for breeding. It takes 5-7 generations of selfing to select a good single plant to breed a stable self-incompatibility line , Some varieties have poor

Example Embodiment

[0040] In the following, the present invention will be further described in conjunction with the embodiments.

[0041] The present invention includes the following steps:

[0042] 1) Tissue culture of broccoli side branches

[0043] 1.1) Broccoli collateral tissue culture seedling culture

[0044] In mid-June, select the parent of the field broccoli self-incompatible line with low seed setting rate (Qing 0577). After the seed is harvested on July 3, 120 plants will be dug out, and the main branches, side branches and old diseased leaves of the plants will be removed and moved. Plant it in a pot containing the nutrient soil for Danish Pinshi vegetables. During the high temperature period, build a shed to keep the soil moist. After planting live trees, apply 10g urea to each pot, and spray the leaves with 0.2% potassium dihydrogen phosphate plus 0.25% boric acid solution every 7 to 10 days. Face 1 to 2 times to promote the germination of side branches. On July 13th, the first batch o...

Abstract

The invention discloses a broccoli lateral branch cultivating plant and a hybrid seed production method. The method comprises the following steps of: 1, broccoli lateral branch tissue cultivating: 1.1 cultivating the cultured seedlings of a broccoli lateral branch tissue; 1.2 cultivating another parent of the broccoli lateral branch tissue; and 2, hybrid seed production: 2.1 preparing soil and applying a fertilizer; 2.2 timely transplanting; 2.3 managing the field; 2.4.1 adding the fertilizer to raise the seedlings; 2.4.2 adding the fertilizer for flower bud differentiation; 2.4.3 applying an expanding fertilizer for broccoli flowers; 2.5 cutting the broccoli flowers; 2.6 pruning; 2.7 managing in a flowering phase; 2.8 controlling insects; and 2.9 harvesting seeds. Broccoli lateral branches are adopted for tissue cultivating and expanding propagation; the method is simple in operation, particularly easy to master and low in cost; technical supports are provided for broccoli hybrid seed production; complicated tests do not need to be carried out in laboratories; and the method has strong technicality and is beneficial to production and popularization.

Description

technical field [0001] The invention relates to a method for cultivating broccoli, in particular to a method of tissue culture through lateral branches of broccoli, and also relates to a hybrid seed production method of broccoli from two different parents, belonging to the technical field of cruciferous vegetable cultivation. Background technique [0002] Broccoli (Brassica oleracea L.var.italica planch), also known as broccoli and arborescent cauliflower, belongs to the genus Brassica in the family Brassicaceae. It is a variety of Brassica oleracea and is native to the Mediterranean region. Broccoli forms a green plump flower ball on the top of the main stem, and collects the tender stems of the flower buds for consumption, because it is rich in vitamins A, B, C, E, protein, anthocyanins and minerals and other nutrients, among which vitamin C is higher than that of Chinese cabbage, tomato, and celery. The meat is crisp and tender, with a sweet flavor, rich nutrition, and e...
